The new Art of Electronics (3rd edition) has an excellent chapter on BJT's. There is first an introduction that uses a simplified transistor model (collector current = beta * base current). Later the Ebers-Moll is explained and used for the rest of the chapter.
The old blue Gray & Meyer book was our go-to when we
(whole departments of IC designers) were working mainly
bipolar technologies. Later versions became more CMOS-
centric.

Solid State Electronic Devices by Ben G. Streetman and Sanjay K. Banerjee is another good one for understanding basics of solid state devices.
Also you can follow this link to have a good understanding **broken link removed**.
I hope it helps.
